Question

I have an array of search values that I would like to use in conjunction with a LIKE query in an NSPredicate:

NSPredicate *p = [NSPredicate predicateWithFormat:@"textField IN LIKE[c] %@", array];

This doesn’t work, but is this possible to see if textfield has any LIKE comparisons to each value in the array?

Answer 1

You should use NSCompoundPredicate. It let’s you combine a series of LIKE predicates with OR.

NSMutableArray *subpredicates = [NSMutableArray array];
for(NSString *text in array)
 [subpredicates addObject:[NSPredicate predicateWithFormat:@"textfield LIKE %@",text]];
NSPredicate *finished = [NSCompoundPredicate orPredicateWithSubpredicates:subpreds];//Your final predicate
